AB - Theoretical and experimental study of acoustic velocity in vapor-liquid  mixture that contained close-packed layer of spherical particles was  performed with respect to nonstationary heat transfer between mixture and  particles in compression half-wave. Theoretical model allows to explain the  decay of equilibrium acoustic velocity compared to its adiabatic value in  case of increasing of void fraction in the mixture. Calculated results are in  agreement with experimental data, obtained in vertical channel with  vapor-liquid filtration with close-packed layer of spherical particles of  borosilicate glass, steel and lead.
